After all that has been said through centuries of literature on the subject of love, it is certainly difficult to be original; but Hartmann has at least the merit of presenting it in a more abstract light, and from a less alluring standpoint than any other writer who has handled the subject. For love, according to his views, is either contrary to the laws of society, and as such environed by perils and pains, vice and degradation, or it is perfectly legal, and, in that case, quickly extinguished. "In the majority of cases," he says, "insurmountable obstacles arise between the two lovers and cause a consequent and immense despair, while in the rarer and more fortunate instances the expected happiness turns out to be purely illusory." It is, however, as hard to love as it is not to love; but he (Hartmann) says, "Who once recognizes that the happiness which it offers is but a chimera, and that its pains are greater than its pleasures, will, while unable perhaps to escape entirely from its allurements, be none the less able to judge it differently from the novice, and therefore capable of diminishing some of its suffering, and some of the disproportion between its joys and its sorrows." According to this savage moralist, then, love is either an illusory and quickly vanishing happiness, or an actual suffering, and resembles hunger precisely in that it is in itself and to the individual a veritable curse. Hartmann judges marriage with an epigram borrowed from Lessing: "There is, at most, but one disagreeable woman in the world; it is only a pity that every man gets her for himself." In very much the same manner are the ties of family and friendship weighed and judged. Scattered here and there is some reflection of Schopenhauer's wit and wisdom, but generally the discussion is defective, and lacks the grace of style and purity of diction which characterized the latter writer. The sentiments of honor, public esteem, ambition, and glory depend, he says, on the opinion of others, and are therefore merely toys of the imagination, "for my joys and troubles exist in my mind, and not in the minds of other people. Their opinion concerning me has merely a conventional value, and not one which is effective for me."
